Application filed November 15, 1923. Serial No. 674,958.

To all W/l om. may concern Be it known that 1, GRANT L. Housman,

a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Window Screens; and I do declare the following to be a full, clear, and exact description of the inven tion, suchas will enable others skilled in the art to which it appertains tomake and use the same.

My inventionrelates to window screens of the type which employs an elongated casing to extend between the vertical sides of a window frame, to contain a screen winding roller. A similar screen is shown in. my U. S. Patent No. 1,282,803 of July 10, 1917. In the patented structure, channel-shaped guides were provided at the ends of the easing, containing a pair of shoes to be forced outwardly by set screws for the purpose of engaging the window frame and securing the casing in place. It was foundhowever, that when the screws were tightened, the channel-shaped guides had a tendency to spring or bend inwardly so that the shoes were not forced into contact with the frame as effectively as necessary. It is one object of thepresent invention to pro'vide'an improved structru'e in which this ditiiculty-is overcome ina simple and effective manner.

in the patented device, the lower end of the screen is metal-bound and the binding carries a pair of spring-projected rods or bolts for engaging the window frame and holding the screen in lowered position, but no provision was made for detachably con necting the binding with the screen, to permit new screen wire to be substituted for the old, or to allow a damaged lower end of Figures 2 and 3 are horizontal sectional wiews as indicated by lines 22 and 3-3 of Fig. 1. i l

F1 gure i is an elevation showing the inetal;

binding for the lower end of the screen.

Figure is a perspective View of one of the improved end structures for the casing. In the drawing above briefly described, the numeral 1 designates a horizontally elongated casing adapted to extend between the opposite sides of a window frame, said casing containing a spring-wound roller 2 upon which a screen 3 is wound. The end plates 4 of the casing 1, are of novel construction. The vertical inner edge portion of each end plate 1-, is bent inwardlyinto parallel relation with the axis of the casing, to provide a vertical shoulder 5 and is then extended outwardly at right angles as indi cated at 6, to form a vertical flange disposed in a plane parallel with and spaced inwardly from the plane of the body-portion of the endplate. The flange 6 and shoulder 5, provide a right angular seat fora portion of the window frame. The flange 6 is of greater height than the body portion ofthe end plate 1 and it extends a considerable distance below said plate, the lower end por-' tion of said flange being bent horizontally inward to provide a ledge 7 and being then extended downwardly as at 8 to provide one side wall of a vertically elongated channelshaped shoe guide or housing 9, the front and rear walls 10 and 11 of the guide 9, and. its lower end wall 12, being formed by bonding portions of the wall 8, the lower end portion of the flange 6 being sufficiently enlarged to permit this formation. The outer side of the housing 9 is open, and its walls 7, 10 and 12 terminate substantially in the plane of the flange 6. The front wall 11 is disposed in substantially the same plane as the shoulder 5 and extends outwardly be yond the plane of the flange to substantially the inner edge of the shoulder 5, and has its upper end 13, soldered or otherwise secured to the lower end of said shoulder so that the channel-shaped shoe guide 9 is body portion of the end plate 4:. A shoe 14;

is received in the guide 9, under a transverse guide strip 15 therein, and a set-screw isthrea'ded through the side wall 8 of said guide, to project the shoe outwardly against the frame. Regardless of the extent to which this screw is tightened, it will be seen that the guide 9 cannot spring inwardly, due to the tact that its widened side wall 11 is secured at its upper end to the shoulder 5.

As in the patent above reterred. to, the ledge 7 is instrumental in supporting an ad justable bracket 17 carrying av roller 18 which disposes the screen 3 in the proper vertical plane, as it passes out of the easing 1.

The lower end of the screen 3 is bound by astrip of sheet metal 19 which is bent upon itself to provide a pair of upstanding flanges 20 and 21 to receive the screen 3 between them the upper portions of these flanges being secured against opposite sides oi the screen by bolts The flange 21 is outwardly stampe throughout its length to provide a receivingchannel 23 for a pair of spring-projected rods or bolts 24; which engage the sides of the window frame to hold the screen in lowered position. a

Any details of construction illustrated but not described, are fully disclosed in Patent- 1,232,803, above referred to.

As excellent results are obtainable from the improvements shown, the details illustrated are preferably followed, but within the scope of the invention as claimed, minor changes may be made.

Obviously, the casing may be used either at the upper end of the lower sash or at the upper end of the upper sash. It will be further understood that the outer ends ot the bolts 241; may be grooved or otherwise formed to insure good engagement with the frame.

I claim:

A device of the class described comprising a roller receiving casing to extend between opposed sides of a window frame, end plates for said casing, each of said plates having its inner vertical edge portion bent inwardly into parallel relation with the axis 0t said casing to form a vertical shoulder and then extended outwardly at right an les to said shoulder to provide a vertical flange disposed in a plane parallel with and spaced inwardly from the plane of the body portion of the end plate and a substantially rectangular shaped shoe housing; joined to the lower end of said flange, the outer side of said housing opening outwardly and having its upper, lower and rear walls terinii'iating substantially in the plane of said flange, the front wall of said housing be ing disposed substantially in the plane of said shoulder and extending; outwardly beyond the plane of said flange to substantially the outer edge oi said shoulder and being secured to said shoulder, whereby to prevent relative springing o'l said housing and said shoulder.

In testimony whereof I have hereunto atfixed my signature.

GRANT L. HOUSTEAU.
